Document Type and Number:
Japanese Patent JP7105862
Kind Code:
B2
Abstract:
A camera optical lens is provided, including from an object side to an image side: a first lens having positive refractive power; a second lens having negative refractive power; a third lens having negative refractive power; a fourth lens having positive refractive power; and a fifth lens having negative refractive power. The camera optical lens satisfies following conditions: 0.70≤f1/f≤0.90; −35.00≤f3/f<−10.00; 4.0≤R3/R4≤12.00; 3.00≤(R5+R6)/(R5−R6)≤20.00; and 2.00≤d7/d8≤4.50. The above camera optical lens may meet design requirements for wide angle and ultra-thinness, while maintaining a high imaging quality.
